Definition, Meaning & Synonyms

reradiation

Noun

/ˌriːˌreɪ.diˈeɪ.ʃən/

Definition

The process by which energy is emitted again after being absorbed, particularly in the context of thermal energy radiating from surfaces.

Examples

The reradiation of heat from the Earth’s surface affects local climates.
Buildings designed with optimized sources of insulation minimize reradiation, keeping interiors cooler.
During the day, solar panels absorb sunlight, and their reradiation can be harnessed for energy use.

Meaning

Reradiation refers to the emission of energy, often in the form of heat or light, that occurs after an object has absorbed energy from another source. It is a crucial concept in thermodynamics and environmental science, particularly when discussing how heat is transferred and retained in various materials and the atmosphere.
